Home Addition vs. Moving: Which Makes More Sense?

Your family has outgrown your home, or you need a space that works differently than the one you have. Before you start scrolling listings, it is worth doing the calculation honestly: is it better to add on to your current home, or sell and buy something that already fits?

In BC’s current market, the answer is more often addition than people expect. Here is how to think through it.

The Real Cost of Moving in BC

Most people underestimate the total cost of selling their home and buying another. Beyond the purchase price of the new property, consider:

• Real estate commission on the sale: typically 3 to 5% of the sale price
• Property transfer tax on the purchase: 1% on the first $200,000, 2% on the balance up to $2 million, 3% above that
• Legal fees, inspection, appraisal: typically $3,000 to $6,000
• Moving costs and temporary housing if there is a gap between possession dates
• Renovation costs on the new home to make it actually work for your family

On a $900,000 home sale and repurchase in the Fraser Valley, these transaction costs can easily reach $50,000 to $80,000 before you have done anything to the new property. And you still may not have the layout you want.

What a Home Addition Actually Costs

Addition costs in BC vary depending on size, complexity, and finish level, but as a rough benchmark, expect $250 to $450 per square foot for a well-built addition in the Fraser Valley, including design, permit drawings, and construction.

A 500 square foot addition to add a primary bedroom, bathroom, and expanded living area would typically fall in the $125,000 to $225,000 range. That same investment in transaction costs to move, plus the renovation you would likely do on a new home anyway, often exceeds what a well-designed addition costs, and you keep the yard, the neighbourhood, and the home you already know.

When an Addition Makes More Sense

The Permit and Design Question

Any addition in BC requires permit drawings and municipal approval. The permit process for a residential addition typically takes one to three months in the Fraser Valley, depending on the municipality and the completeness of the drawing set submitted. Getting drawings done right the first time avoids resubmissions and keeps the project on schedule.

At Rexford, we handle the design and permit drawings for additions across BC. If you are weighing whether an addition makes sense for your property, a conversation with us early in the process will give you a realistic picture of scope, cost, and timeline before you commit to anything.

The Question Worth Asking First

Before deciding between an addition and moving, ask: what is actually wrong with my current home? If the answer is the neighbourhood, the commute, or the lot, an addition will not fix it. If the answer is square footage, a bedroom, a bathroom, or a better kitchen layout, an addition almost always makes more financial sense than moving in BC’s current market.

The best additions are ones that feel like they were always part of the original house. That comes from good design and a team that understands how the existing home works before they start drawing what is new.
